so as to = in order to一样,“以便,为的是.”,后面跟目的状语；
例如：Please check the list carefully so as to avoid mistakes.
so +形容词/副词+as to,“如此...以至于...”,后面跟的是结果状语
例如：I get up early so as to arrive at school on time.
so as to既可表示目的,又可表示结果,其位置一般在句中,
否定结构用so as not to ；
Eg：He ran quickly so as to catch the last bus.
他跑得很快以便赶上那末班车.
so.as to只能表示结果,
否定结构用so.as not to .

新生命语言团倾情为您解答~so as to 引导结果状语时咋翻译？，给个例子吧，谢谢so as to后只能跟目的状语啊。。
